An explosion aboard the Eco Wizard tanker at the Ust-Luga port in Leningrad Oblast caused an ammonia leak on July 6, prompting an emergency response.

Russian authorities said the ammonia leak at Ust-Luga was minor.

An explosion occurred on the Eco Wizard tanker in the Russian port of Ust-Luga, which probably caused an ammonia leak.

The explosion occurred on board the vessel during ammonia loading at the terminal of MCC Eurochem JSC.

This caused holes in the hull of the ammonia carrier, through which water began to pour in. The ship began to sink, and the crew was evacuated to shore.

Since the beginning of the year, this is the sixth tanker to call at Russian ports and suffer an explosion.
